Instructions for my vehicle were not accurate for both the Pedal Tune and ECU Tuning Box. Pls check your diagrams for the BMW X5 E70, N63 engine!
Great customer support!
Fast delivery, had an initial issue with one of the connections, but 1 phone call and a technical email later all resolved., I have tried racechip previously but I am more impressed with this company.
all very well
When I ordered, there was no stock for the particular car I owned. I waited one week for the stock but had to write in to check what was the status. However, I must say the response was good.
